Specification of Letters Patent.

Application filed August 18, 1919. Serial No. 318,121.

To all whom-it may concern:

Be it"known that I, JOHN S. BRENNAN, a citizen of the United States, andresident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in Wicks;and I do hereby declare that the following 1s a full, clear, andexact'description thereof.

My invention pertains to new and useful 5 improvements in. annular wicksfor use in the burners of heating and cooking stoves which burn gaseousor liquid hydro-carbons as a fuel.

It is well recognized that cotton and other vantages of both of thesetypes of wicks may be overcome by the use of a woven wick formed ofthreads or cords-of asbestos. It

is therefore the primary object of the invention to construct an annularwick of such material. 7

It is also an object of the invention to provide a wick, the'usefulnessof which will be more than twice as great as that of the average wick ofthis character, this being carried out by the provision of a burningedge on each peripheral edge of the annular wick.

A still further object is to provide a combi ned supporting strip forthe wick material together with means for preventing the unraveling ofthe non-selvaged edges of the same. v

- With these 'and other objects and advantages in view the inventionresides in the novel features of construction and combination of partswhich will be hereinafter particularly described. and claimed.

Referring to the drawing forming part of this application,

Figure 1 represents a planview of an annular wick constructed inaccordance with my invention. 1

Fig. 2 is a plan view of the metallic supporting strip used inconnection with the strip of wick material.

Fig. 3 is a similar view of the wick before the same has been bent incircular shape.

In one vaged edges ofthe strip .strip 1 so as Fig. 4 is an enlargedfragmentary view of a portion of the strip of wick material showing themanner in which thesame is woven to form a strip of predeterminedwidth'and havlng 1ts opposite longitudinal edges sel-.

vaged. 1

Fig. 5 is a transverse sectional view taken substantially on the planeof the line 55 of Fig. 1.

In the-illustratedembodiment of the invention as depicted in the drawingthe numeral 1 denotes a strip of wick material of predetermined length,said strip being a portion of a strip of indeterminate length. In otherwords the wick material can be woven in strips of any length and thencut into sections of the required length. As Fig. 4 the wick materialconsists. of warp and woof threads or cords of asbestos woven togetherin an ordinary manner so that the opposite or longitudinal edges areselvaged.

The wick in addition to the strip of wick Patented Jan. 13, 1920.

shown 1n STATES PATE OFFICE; A

material includesa metallic supporting strip 2 of a length greater thanthe length of the strip 1. The supporting strips 2 are preferably formedby stamping the same from blanks of very light gage sheet metal. Eachconsists of a pair of parallel bars 3 and a plurality of transverse bars4 together with end plates 5 which extend transversely of the bars 3 andare substantially of '-a length 7 equal to the width of the strip 1. Theintermediate portion of the metallic strip 2 between the end plateportions 5 thereof, or in other words the is less than the width of thestrip 1. The ends of the transverse bars 4 beyond the outer edges of thebars 3 terminate in V prongs 6.

In making up a wick from one of the strips 1 of wick material and oneof-the metallic strips 2, the latter is plac'ed on the former andextended longitudinallythereof with the longitudinal edges of the bars 3equally spaced from the longitudinal sel- 1. When the prongs 6 are bentlaterally and forced into the wick strip 1 and then clenched as shown inFig. 5, the two strips are efiectively held together. The end plates arethereafter bent longitudinally of themselves or transversely of the toembrace the transverse unselvaged edges thereof. This will prevent suchedges from becoming unraveled as .is obvious. The operation of straightstrips 1 and 2 into circular form as distance betweenthe bars 3,

shaping the shown in Fig. 1 completes the operation of forming a wick ofthe character described.

In view of the fact that theimmediate portions of the strip 2- arespaced inwardly of the longitudinal peripheral edges of the strip 1, andsince these last mentioned edges are selvaged, the wick can be disposedto present either of said selvaged edges as a burning edge. Thus oneedge may be used until it becomes frayed or otherwise mutilated orclogged, whereupon by reversing the wick a new and clean burning edge ishad. Furthermoreif so desired'one of the metallic strips 2 may be usedan indefinite number of times merely by placing a strip of wick materialsuch as the original strip when the latter' becomes worn or otherwiserendered ineffective. Various changes may be made in the form andproportion and in the manner of assembling the several parts of theinvention Without departing from or sacrificing any of the featuresthereofQ I claim:

. 1. An improved wick comprising a woven asbestos strip having itslongitudinal edges selvaged, said strip being shaped to form a rin withits non-selva ed ed es ad'acent V b O 21 tos strip to prevent the samefrom unravand parallel, and means for preventing said non-selvaged edgesfrom unraveling.

2. An improved Wlck comprising a woven asbestos strip having itslongitudinal edges 'selvaged, said strip being shaped to form a ringwith its non-selvaged edges adjacent and parallel, and a supportingmetallic ring having the asbestos ring secured thereto, a portion of themetalhc ring being ben'taround the non-selvaged edges of the asbeseling.v. 3

3. An lmproved w1ck comprlsing a rectangular strip of wick material anda metallic strip secured to the strip of wick ma-- terial and having itsintermediate portion of less Width than the width of the latter, the

opposite end portions of the metallic strip termediate portion of lesswidth than the width'of the woven strip, the opposite end portions ofthe metallic strip being substantially the same width as the woven stripand bent around the non-selvaged edges of the latter to prevent the samefrom unraveling, said strip being shaped to form a ring.

5. 'An improved wick comprising a rectangular st-rlp of woven material,a metallicstrip of rectangular shape disposed in contact with the otherstrip and having its intermediate portion of less width than the widthof the filst mentioned strip, the opposite end portions of the. metallicstrip being of substantialy the same width as the width or the firstmentioned strip and bent around the transverse edges of the latter,

and prongs extending from the longitudinal edges of the intermediateportion of the metallic strip and bent into the other strip to securethe two strips together, said strips be ing shaped to form a ring.

In testimony that I claim the foregoing I,

have hereunto set my hand at Milwaukee, in the county of Milwaukee andState of WIS- consin. I
